mCi/kg = µBq/kg × 2.702702703e-14
About Microbecquerels per kilogram
The microbecquerel per kilogram (µBq/kg) equals 10⁻⁶ Bq/kg. Very low-level anthropogenic contamination in drinking water (tritium, ⁹⁰Sr) and dietary exposures from global nuclear weapons test fallout in the 1950s-1960s are characterised at µBq/kg in body burden assessments. 1 µBq/kg = 10⁻⁶ Bq/kg = 10⁻³ mBq/kg.
About Millicuries per kilogram
The millicurie per kilogram (mCi/kg) equals 3.7 × 10⁷ Bq/kg = 37 MBq/kg. Radiopharmaceutical preparations are sometimes characterised in mCi/kg when assessing organ uptake per body mass; ⁹⁹mTc-labelled compounds have specific activities in the mCi/µmol range that translate to high mCi/kg values. 1 mCi/kg = 3.7 × 10⁷ Bq/kg.
